The Influence of Slots in Heat Sink Fins within a Cavity, with/without Internal Bodies, Filled with a Hybrid Nanofluid [PDF]

open access: yesJournal of Applied and Computational Mechanics
Natural heat transfer is studied in a square enclosure containing a heat sink in the presence of a hybrid nanofluid (MWCNT and Fe3O4). The right wall is kept cool (Tc), while the left wall is hot (Th), and the upper wall and lower wall are thermally ...

The role of education in promoting circular economy

open access: yesInternational Journal of Sustainable Engineering, 2023
The environmental problems caused by a linear economy system and the exploitation of natural resources have been known well over 50 years. Although a great deal has been done, there is a contradiction between increasing consumerism and the concrete ...

On the Uniqueness of Co-circular Four Body Central Configurations

open access: yesArchive for Rational Mechanics and Analysis, 2021
We study central configurations lying on a common circle in the Newtonian four-body problem. Using a topological argument we prove that there is at most one co-circular central configuration for each cyclic ordering of the masses on the circle.

Numerical analysis of two and three dimensional buoyancy driven water-exit of a circular cylinder

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2014
With the development of the technology of underwater moving bodies, the need for developing the knowledge of surface effect interaction of free surface and underwater moving bodies is increased. Hence, the two-phase flow is a subject which is interesting

Wind-load, pressure and velocity measurements: post processing and discussion

open access: yesEPJ Web of Conferences, 2014
Because of the practical importance of bluff bodies subjected fluid flow, fluid dynamics around two-dimensional bluff bodies, especially circular cylinders, has been studied in light of three major parameters, namely flow-induced force, surface pressure ...

Applications of implicit constitutive theory for describing the elastic response of rocks and concrete

open access: yesArchives of Mechanics, 2022
An implicit constitutive relation is proposed for elastic bodies, when the gradient of the displacement is assumed to be very small, and as a result the strains are small.

On Centered Co-circular Central Configurations of the n-Body Problem [PDF]

open access: yesJournal of Dynamics and Differential Equations, 2018
We study the co-circular central configurations of the n-body problem for which the center of mass and the center of the common circle coincide. In particular, we prove that there are no central configurations of this type with all the masses equal except one.

Circular RNAs: Crucial regulators in the human body (Review)

open access: yesOncology Reports, 2018
Circular RNAs (circRNAs) belong to a new type of endogenous non‑coding RNAs (ncRNAs) that are derived from exons and/or introns, and are widely distributed in mammals. The majority of circRNAs have a specific expression profile in cells or tissues, as well as during different stages of development. CircRNAs were originally thought to be the products of

Periodic Solutions for Circular Restricted -Body Problems [PDF]

open access: yesAbstract and Applied Analysis, 2013
For circular restricted -body problems, we study the motion of a sufficiently small mass point (called the zero mass point) in the plane of equal masses located at the vertices of a regular polygon. By using variational minimizing methods, for some , we prove the existence of the noncollision periodic solution for the zero mass point with some fixed ...
